If you're doing CPU folding and have an AVX-capable CPU, make sure you're running a current version of the client; I believe this is necessary in order to properly detect AVX capability. There are some AVX-optimized WUs in the wild (GRO_A7 core), and I'm seeing production rates in excess of 30K PPD on an FX-8350 when it manages to snag an AVX WU.

I don't fold, but additional results from people folding with AVX-enabled workloads would be very interesting.Uber-bonus points if you happen to be using a Xeon Phi to do it (although I'm not holding my breath).
